Anterior Loop of the Inferior Alveolar Canal: A Cone-Beam Computerized Tomography Study of 494 Cases.

The aim of this study was to use cone-beam computerized tomography (CBCT) images of patients to assess the prevalence of different types, especially anterior loop, of the mental portion of the inferior alveolar canal and to evaluate the anterior loop lengths. CBCT images of 494 patients providing inclusion criteria were examined by 2 oral radiologists. Sagittal, axial, and multiplanar reformatted images were used to detect the type of mental portion of the inferior alveolar canal.

Diagnostic accuracy of cone-beam CT compared with panoramic images in predicting retromolar canal during extraction of impacted mandibular third molars.

Objectives: The clinical significance of the existence of a retromolar canal and of its neurovascular content is not yet clear.The aim of the present study was to assess the visibility, diameter and course of the mandibular retromolar canal (MRC) using cone beam computed tomography (CBCT) scan--had been taken for pre-operative radiographic evaluation of impacted mandibular third molars--compared to panoramic radiographs.

Study Design: Subjects eligible for study enrollment were those who underwent preoperative CBCT scan for the extraction of impacted mandibular third molars were determined to be extremely close to the mandibular canal on panoramic radiographs.

Cone beam computed tomographic analyses of the position and course of the mandibular canal: relevance to the sagittal split ramus osteotomy.

Purpose: The aim of this study was to document the position and course of the mandibular canal through the region of the mandibular angle and body in dental patients, using cone beam computed tomographic imaging.

Methods: The position and course of the mandibular canal from the region of the third molar to the first molar were measured at five specific locations in the same plane: at three different positions just between the first and second molars; between the second and third molars; and just distal to the third molar.

Results: The study sample was composed of 500 hemimandibles from 250 dental patients with a mean age of 26.

Lateral lingual vascular canals of the mandible: a CBCT study of 500 cases.

Purpose: The aim of the present study was to use cone-beam computed tomography (CBCT) images of patients to assess the localization, diameter, and course of the lateral lingual vascular canal (LLVC).

Methods: CBCT (Morita, Accuitomo 170) images from 500 patients were used in the present study. The CBCT images were examined by two oral radiologists.

Assessment of the visibility and characteristics of the mandibular incisive canal: cone beam computed tomography versus panoramic radiography.

Purpose: The aim of this study was to assess and compare the visibility, diameter, and course of the mandibular incisive canal (MIC) using cone beam computed tomography (CBCT) and panoramic radiography.

Materials And Methods: CBCT images and panoramic radiographs from 243 patients were used in this study. Standard exposure and patient positioning protocols were used for all the patients.

The development and organization of newborn screening programs in Turkey.

Background: Newborn screening tests have been designed to identify infants with severe disorders that are relatively prevalent and treatable or controllable. Comparing to other countries, the incidence of these diseases are very high in Turkey where the rate of consanguineous marriage is high.

Methods: In this article, it is aimed to evaluate the development and organization of newborn screening programs in Turkey which include phenylketonuria, congenital hypothyroidism and biotinidase deficiency screenings.

Infantile malignant osteopetrosis: report of 2 cases with osteomyelitis of the jaws.

Infantile malignant osteopetrosis (IMO) is an uncommon autosomal recessive disease characterized by dense, brittle, sclerotic, radiopaque bones, which generally results in neurological and hematological abnormalities. In general, IMO is fatal, as patients fail to grow and expire due to complications of the disease such as severe chronic anemia, bleeding, and/or infections. In children with IMO, the development of the dentition is seriously disturbed.

Detection of bifid mandibular condyle using computed tomography.

Objective: To determine the frequency and characteristics of bifid mandibular condyle (BMC) using computed tomography (CT) evaluation.

Study Design: A retrospective study was carried out using the CT records of 550 patients referred to the Medical School of Erciyes University (Kayseri, Turkey) between 2007 and 2010. T-tests were used to compare frequency of BMC between the left and right sides and between female and male patients.

Detection and characterization of the mandibular accessory buccal foramen using CT.

Objective: To investigate the frequency and characteristics of the mandibular accessory buccal foramen (ABF) with CT.

Methods: A retrospective study was carried out using the CT records of 504 patients referred to the Erciyes University Medical School (Kayseri, Turkey) between 2007 and 2010. Presence, location, diameter, area and number of ABFs and their continuity with mandibular canal and distance to the mental foramen were evaluated using axial, sagittal and three-dimensional CT images.

An unusual case of multilocular Stafne bone cavity.

Stafne bone defects (SBDs) are asymptomatic lingual bone depressions of the lower jaw that are frequently caused by soft-tissue inclusion. The common variant of SBD exists at the third molar region of the mandible below the inferior dental canal is an and ovoid-shaped homogeneous well-defined radiolucency. In this report, an unusual occurrence of SBD with multilocular appearance is presented.

Prevalence of bifid mandibular condyle in a Turkish population.

The aim of this study was to determine the frequency of bifid mandibular condyle (BMC) using panoramic radiographs supported by different radiographic techniques. A retrospective study was carried out by evaluating panoramic radiographs of 18,798 patients referred to the Department of Dentomaxillofacial Radiology. T-tests were used to compare the frequency of BMC between left and right sides and between female and male patients.

Tetrafid mandibular condyle: a unique case report and review of the literature.

Morphological changes such as bifid and trifid mandibular condyle are rare entities. The aim of the present report is to describe a unique morphological variation of the mandibular condyle which has four separate condylar heads (tetrafid mandibular condyle) and to discuss clinical and radiological differential diagnosis of tetrafid mandibular condyle with advanced imaging techniques.

Anterior Stafne bone defect mimicking a residual cyst: a case report.

Stafne bone defects (SBDs) are asymptomatic lingual bone depressions of the lower jaw that are frequently caused by soft tissue inclusion. The common variant of SBDs exists at the third molar region of the mandible below the inferior dental canal and has been mostly diagnosed incidentally during routine radiographic examination. The anterior variant of a SBD (ASBD) is relatively uncommon and is located in the premolar region of the mandible.
